October 2025 ISSB update

The International Sustainability Standards Board (ISSB) met on 28 October 2025 to discuss developments across Biodiversity, Ecosystems and Ecosystem Services, Human Capital, and Amendments to Greenhouse Gas Emissions Disclosures.

While no decisions were made on Biodiversity, Ecosystems and Ecosystem Services and Human Capital, the ISSB explored drawing on the Taskforce on Nature-related Financial Disclosures (TNFD) framework and refining its research approach.

In contrast, the ISSB tentatively decided to amend the Sustainability Accounting Standards Board (SASB) Standards to align with upcoming changes to IFRS S2 Climate-related Disclosures by amending the financed emissions metrics in the Asset Management & Custody Activities, Commercial Banking and Insurance SASB Standards. These amendments are set to take effect from 1 January 2027, with early application permitted, and are expected to be formally issued in December 2025.
